Abstract
Description
Technical Field
[0001] This utility model belongs to the field of fabric dyeing technology, and in particular relates to a device for fixing reactive dyes for fabrics. Background Technology
[0002] In the textile printing and dyeing industry, the reactive dye fixing equipment for fabrics is the key equipment to achieve a firm bond between reactive dyes and fibers. After dyeing with reactive dyes, a high temperature and high humidity environment is required to promote a chemical reaction between the dye and the fiber, thereby improving color fastness and dyeing effect. The fixing equipment provides the necessary environment for the fixing reaction by spraying steam onto the fabric or applying other treatment conditions. Its performance directly affects the dyeing quality and production efficiency of the fabric.
[0003] Currently, most reactive dye fixing equipment for fabrics on the market adopts a single-sided steam jet structure. This structure typically consists of a steam generator, a single jet frame, and a fabric conveying device. The steam generated by the steam generator is transported to the jet frame through a single pipe, and then the steam is sprayed onto one side of the fabric from the nozzles on the jet frame. At the same time, the fabric completes the color fixing process under the traction of the guide shaft.
[0004] However, existing reactive dye fixing equipment for fabrics has the following defects in actual use: First, the single-sided steam jetting method results in uneven steam contact between the two sides of the fabric, which easily leads to obvious color difference between the front and back of the fabric. In addition, the single-path steam inlet structure of the jetting frame causes pressure loss along the steam path, resulting in an imbalance of steam volume at the upper and lower ends of the jetting frame, which seriously affects the consistency of color fixing. Second, existing reactive dye fixing equipment for fabrics lacks a fabric limiting structure. Under the action of steam impact, the fabric is prone to large-scale shaking, wrinkling or displacement, which not only affects the color fixing effect, but may also lead to local dyeing overlap or poor color fixing.
[0005] Therefore, it is essential to invent a device for fixing reactive dyes in fabrics. Utility Model Content
[0006] To address the above problems, this utility model proposes a reactive dye fixing device for fabrics, and the technical solution used is as follows:
[0007] A reactive dye fixing device for fabrics includes a housing, positioning frames, a spraying mechanism, a steam generator, a guide shaft, a motor, a feed inlet, and a discharge outlet. The spraying mechanism is fixed inside the housing by several positioning frames. The input end of the spraying mechanism is fixed to the output end of the steam generator, which is placed on the ground on one side of the housing. The output end of the steam generator faces the fabric, and the fabric passes through a corresponding guide shaft. Both ends of the guide shaft are rotatably connected to the inner wall of the housing via support bearings. One end of the guide shaft is fixed to the output end of a corresponding motor, and the motor base is fixed to the housing by bolts. A feed inlet is provided on the lower side of the housing, and a discharge outlet is provided on the upper side of the housing.
[0008] Furthermore, the spraying mechanism includes a gas supply pipe, a first transfer pipe, a second transfer pipe, and a spraying frame. The input end of the gas supply pipe is fixed to the output end of the steam generator via a connector. The gas supply pipe has two output ends, one of which is fixed to the first transfer pipe via a connector, and the other output end is fixed to the second transfer pipe via a connector. There are two spraying frames, each fixed inside the outer casing by a positioning frame, and the spraying frames are mirror-shaped, with their output ends facing the corresponding sides of the fabric. The lower ends of the spraying frames are fixed to the first transfer pipe via connectors, and the upper ends of the spraying frames are fixed to the second transfer pipe via connectors. This arrangement allows the steam generated by the steam generator to be sprayed onto the fabric.
[0009] Furthermore, the spray frame includes an annular tube, an array tube, and nozzles. The annular tube is fixed inside the outer shell by a positioning frame, and several array tubes are uniformly fixed inside the annular tube. Several nozzles are fixed to the outer surfaces of the annular tube and the array tubes through joints, and the output ends of the nozzles all face the fabric direction. The lower end of the annular tube is fixed to the first transfer tube, and the upper end of the annular tube is fixed to the second transfer tube. This arrangement can reduce the difference in the amount of steam sprayed from the upper and lower ends and improve the consistency of color fixing.
[0010] Furthermore, the lower end of the outer shell is fixed with a base by bolts, and a slag collection tray is slidably installed inside the base. The upper side of the slag collection tray has a slag collection cavity, and the outer side of the slag collection tray is fixed with a handle by bolts. This arrangement can collect the dye liquid dripping from the fabric.
[0011] Furthermore, several limiting shafts are provided between the two guide shafts, and both ends of the limiting shafts are rotatably connected to the inner wall of the outer casing through support bearings; the limiting shafts are respectively set on both sides of the fabric. This arrangement can prevent the fabric from shaking significantly under the action of steam force.
[0012] Compared with the prior art, the present invention has the following beneficial effects:
[0013] The spraying mechanism of this invention can spray steam on both sides of the fabric simultaneously, thereby avoiding the problem of uneven penetration caused by spraying on one side. Since both ends of the annular tube can receive steam, the difference in the amount of steam sprayed from the upper and lower ends of the spraying frame is small, thus improving the consistency of color fixation. In addition, since the two spraying frames are set vertically, the dye dripping on the fabric will not cause the spraying frames to become clogged.
[0014] The limiting shaft of this invention, being located on both sides of the fabric, can limit the degree of swaying of the fabric and prevent it from swaying excessively under the action of steam. Attached Figure Description

[0024] Please see Figures 1 to 4 As shown, this utility model is a reactive dye fixing device for fabrics, including a shell 1, a positioning frame 2, a spraying mechanism 3, a steam generator 4, a guide shaft 5, a motor 6, a feed inlet 7, and a discharge outlet 8. The spraying mechanism 3 is fixed inside the shell 1 by several positioning frames 2, wherein the input end of the spraying mechanism 3 is fixed to the output end of the steam generator 4, which is placed on the ground on one side of the shell 1; the output end of the steam generator 4 faces the fabric 14, wherein the fabric 14 passes through the corresponding guide shaft 5, and both ends of the guide shaft 5 are rotatably connected to the inner wall of the shell 1 by support bearings; one end of the guide shaft 5 is fixed to the output end of the corresponding motor 6, and the base of the motor 6 is fixed to the shell 1 by bolts; the lower side of the shell 1 has a feed inlet 7, and the upper side of the shell 1 has a discharge outlet 8.
[0025] Specifically, the injection mechanism 3 includes a gas supply pipe 31, a first transfer pipe 32, a second transfer pipe 33, and an injection frame 34. The input end of the gas supply pipe 31 is fixed to the output end of the steam generator 4 via a connector. The gas supply pipe 31 has two output ends, one of which is fixed to the first transfer pipe 32 via a connector, and the other output end of the gas supply pipe 31 is fixed to the second transfer pipe 33 via a connector. There are two injection frames 34, both of which are fixed inside the outer casing 1 by positioning frames 2. 4. The spray frame 34 is set in a mirror image, with the output ends of the spray frame 34 facing the corresponding sides of the fabric 14. The lower ends of the spray frame 34 are fixed to the first transfer pipe 32 through connectors, and the upper ends of the spray frame 34 are fixed to the second transfer pipe 33 through connectors. The air supply pipe 31 can transport the steam discharged from the steam generator 4 to the inside of the first transfer pipe 32 and the second transfer pipe 33. The first transfer pipe 32 and the second transfer pipe 33 can transport the steam to the inside of the spray frame 34, and then spray the steam onto the fabric 14 through the spray frame 34.
[0026] Specifically, the spray frame 34 includes an annular tube 341, an array tube 342, and nozzles 343. The annular tube 341 is fixed inside the outer casing 1 by a positioning frame 2, and several array tubes 342 are uniformly fixed inside the annular tube 341. Several nozzles 343 are fixed to the outer surfaces of the annular tube 341 and the array tubes 342 through joints. The output ends of the nozzles 343 all face the fabric 14. The lower end of the annular tube 341 is fixed to the first transfer tube 32, and the upper end of the annular tube 341 is fixed to the second transfer tube 33. In use, the annular tube 341 can receive the steam delivered by the first transfer tube 32 and the second transfer tube 33 and deliver it to the position of the array tube 342. Then, the steam is sprayed onto the fabric 14 through the nozzles 343. Since both the upper and lower ends of the annular tube 341 can receive steam, the difference in the amount of steam sprayed from the upper and lower ends of the spray frame 34 is small, which improves the consistency of color fixing.
[0027] Specifically, the lower end of the outer shell 1 is fixed with a base 9 by bolts, and a slag collection tray 10 is slidably installed inside the base 9. The upper side of the slag collection tray 10 is provided with a slag collection cavity 11, and the outer side of the slag collection tray 10 is fixed with a handle 12 by bolts. When in use, the slag collection cavity 11 can collect the dye liquid dripping from the fabric 14.

[0028] Specifically, a number of limiting shafts 13 are provided between the two guide shafts 5, wherein both ends of the limiting shafts 13 are rotatably connected to the inner wall of the outer shell 1 through support bearings; the limiting shafts 13 are respectively provided on both sides of the fabric 14. When in use, since the limiting shafts 13 are provided on both sides of the fabric 14, the limiting shafts 13 can limit the degree of shaking of the fabric 14, and prevent the fabric 14 from shaking significantly under the action of steam force.
[0029] Please see Figure 1-4 As shown, this utility model is a reactive dye fixing device for fabric. Its working principle is as follows: When in use, the fabric 14 enters the housing 1 through the feed port 7. Then, through the cooperation of the motor 6 and the guide shaft 5, the fabric 14 is guided to the discharge port 8 and discharged at the discharge port 8. When the fabric 14 moves inside the housing 1, the spraying mechanism 3 can spray the steam generated by the steam generator 4 onto the fabric 14, thereby fixing the reactive dye on the fabric 14 with steam.
